In this special episode, my friend—and fan-favorite guest—Dr. Peter Attia takes the mic as guest host. Peter sits down with legendary trader John Arnold, widely considered the greatest energy trader of all time. Today, through his foundation Arnold Ventures, John applies the same rigorous thinking to some of America’s toughest social challenges—criminal justice reform, healthcare policy, and K–12 education, to name just a few. This interview originally aired on Peter’s excellent podcast The Drive. You can check it out at PeterAttiaMD.com, or subscribe to The Drive wherever you get your podcasts.
